堆排序(Heap-Sort)是堆排序的接口算法,Heap-Sort先调用Build-Max-Heap将数组改造为最大堆,然后将堆顶和堆底元素交换,之后将底部上升,最后重新调用Max-Heapify保持最大堆性质。由于堆顶元素必然是堆中最大的元素,所以一次操作之后,堆中存在的最大元素被分离出堆,重复n-1次之后,数组排列完毕。整个流程如下图: J...

Java实现---堆排序 Heap Sort 堆排序与快速排序,归并排序一样都是时间复杂度为O(N*logN)的几种常见排序方法。学习堆排序前,先讲解下什么是数据结构中的二叉堆。 堆的定义 n个元素的序列{k1,k2,…,kn}当且仅当满足下列关系之一时,称之为堆。 情形1:ki<= k2i且ki<= k2i+1(最小化堆或小顶堆)...

Java code for heap sort Time and space complexity What is heap? A heap is a tree with some special properties, so value of node should be greater than or equal to(less than or equal to in case of min heap) children of the node and tree should be complete binary tree. Binary heaps ...
